- What are you attempting to achieve? (Keep it simple and clear)
- Find a way to fix the rig and have it play the animation just the way it plays in blender. I feel like there’s a issue with the roblox animator importing bones with IK stretch in it. Because it doesn’t seem like it’s added to the rig after playing the animation.
- What is the issue? (Keep it simple and clear - Include screenshots/videos/GIFs if possible)
- After exporting an animation from blender and importing it into roblox through the same bone rig, I encountered issues with the animation. It’s clearly different from the one in blender which has a bigger flap.
See image for reference:
- What solutions have you tried so far? (Have you searched for solutions through the Roblox Wiki yet?)
- I tried baking the animation which didn’t fix it, I tried re-importing a couple of times, I also tried making them into those strip animation thing or I think are NLA strips, the ones that can be seen in Non-linear mode on animation in blender. None of them works.
Extra details you might wanna know:
- The animator is an Animation Controller (since I’ve had horrible experiences with using motor6d being animated with the body and the mesh)
- I’m figuring out just how to import it well without any issues and that’s it, leave the rest to me.
- The mesh contains an IK bone and IK stretching for each bone.

Also incase you might be wondering, the model is basically like the flower monsters from stranger things where it has flaps that open up and spread. Also don’t question my modeling skills plz, I’m not really an expert at it, but yk I’m trying my best so far.
You might need to implement a smart bone module of sorts.

Hello there, could you elaborate? What do you mean by smart bone modules? Examples could help
Im actually suprised you havent heard of a smart bone module speaking your working with slightly advanced animating and such. Heres a few videos on smartbone https://youtube.com/playlist?list=PLfwlNPWSxd9GodG6YKm8Y23tefwIvCAYI&si=Qjc9AslvOuG1jlSZ
I’ve heard of smart bones but I’m confused as to why it would be a solution to a problem like this. The only experience I’ve had with smartbone modules is to add cloth physics.
I was thinking it had something to do with smart bone and rigging because of the major proportion changes between the to photos. Maybe check your Tri count and ensure its below 10K for Roblox importing.
Alright so uhh I just checked and apparently… the whole thing (total count of all parts) is 24k tris, I might try lowering it and then see if there’s any changes.

Alright so update, I tried it first at 12k tris, still the same issue, then I converted it to 10k tris, still the same issue. I tried the same solutions that I tried earlier that didn’t work and well it still didn’t work for this one. I’ll try finding out the issue, testing around stuff, playing around with the size and and stretching and see which one isn’t being imported correctly.
Soo I just found out, it stretches, but it doesn’t resize itself. Is it because bones can’t resize in roblox? The bones changes in size but it only stretches the mesh
I did some research, apparently roblox doesn’t support bone scaling since they’re attachments and could only stretch…
As an alternative, I removed all IK stretches and re-animated and adjusted the rig to meet my preferences. Although it didn’t have the vision I dreamed of, but it’s better than nothing.
Result:
Issue of the problem: Roblox doesn’t support bone scaling which altered the results of the animation that was intended to have bone scaling.
